League Client Shrinking

My client over time, whether I'm playing games or not is simply shrinking it's ratio on it's own. Which wouldn't be an issue if it didn't continue to shrink to where I can barely close and reopen the game! I've looked into it and the issue seems to have been happening three years ago up to now as well without a single fix. Even with trying to redownload it or trying to use the tool for it. Please let me know if this is happening to you and/or how to fix it? I will attach a picture when it happens again!
